i love you doesn't work on me

most, if not all girls i know, feel instantly better when the guy says i love you bla but i just get even more upset. sometimes i wonder why i'm not like them, not that i want to be just like everyone else but i guess they don't stay sad for long because all boys seem to only know to say 'i love you' when they sense something wrong. idky boys think thats the life-saver line. or is it? ah wtv irrelevant.
